A company is redesigning its infrastructure and wants to reduce the number of physical servers in use. Which of the following architectures is best suited for this goal?

Virtualization is the best option because it allows a single physical server to host multiple virtual servers (virtual machines or VMs). This consolidates workloads, significantly reducing the number of physical servers required, thus achieving the company's goal. Serverless computing abstracts away server management entirely but doesn't directly reduce physical server count within the company's own infrastructure. Segmentation divides a network into smaller, isolated segments for security, not server consolidation. Microservices is an architectural style for developing applications as a suite of small, independent services, which doesn't inherently reduce physical server count.
